Developers reminded ‘wildlife needs good neighbours’
Survey reveals how UK’s gardeners support wildlife
Town planners should make biodiversity a core consideration within urban and suburban regeneration plans and purposefully create 'green networks', reveals the Wild About Gardens Discovery Survey, carried out by the RHS and The Wildlife Trusts in partnership with Ribena.
According to the findings, garden owners are responding to wildlife gardening advice and taking action, but there is still considerable room for improvement even among the most wildlife-friendly gardeners. The survey’s findings that mini-habitats are spread between different gardens emphasises the importance of making it easier for wildlife to move within a connected network of 'green corridors' by using trees, ponds and hedgerows, and providing a greater variety of food sources from nectar, berry and seed-producing plants.
Simon Thornton-Wood, Director of Science & Learning for the RHS, explains, "Developers should be careful not to create 'token gesture' green spaces in anticipation they might provide real benefit for wildlife. From our preliminary findings we looked at the gardens that recorded sightings of all five of our key species and found that they nearly all had tall trees, but only a third shared other important features such as ponds, woodpiles and long grass. Not everyone, especially those with small gardens, has the room for the ultimate checklist of features which means that neighbours need to pull together to help improve wildlife communities as well as social ones. Individuals who have created a wildlife oasis in a conservation desert provide a welcome refuge but its value multiplies when connected to neighbouring habitats, as last month’s Stern Report touched upon by calling for greater linkage of 'green' habitats to better accommodate species movement."
More than 1,500 garden owners responded to the survey to help investigate links between garden habitats, gardening practices and key garden species. Participants were asked to complete an inventory of types of plants and features in their garden including the garden's location, their gardening practices, and whether the following species visited their garden within the two-week survey period: hedgehog, goldfinch, common frog, toad, bumblebee, and specifically the brown bumblebee. The data is being analysed in depth with more comprehensive findings will be released next year.
The survey showed while wildlife gardeners are busy supporting the 'attractive' species such as birds, hedgehogs and frogs, they're not so aware of the need to encourage invertebrates, with the possible exception of butterflies, through planting buddleia and sedum. The importance of varying ground cover and shrubs should not be underestimated in supporting the less popular 'creepy crawlies', which play a vital role in the food chain and in making gardens effective as self-sustaining wildlife habitats. These are the sort of perceptions the RHS and The Wildlife Trusts hope to change through Wild About Gardens
Other preliminary findings from the survey include:
- Gardens with seed or nut-producing plants were over three times more likely to attract goldfinches than those with none (72% compared to 22%).
- Nearly twice as many participants who owned a garden pond spotted frogs during the survey period than those without.
- Gardens with a larger area of long grass (over foursquare metres) were more likely to attract brown bumblebees.
- London gardens recorded the lowest average number of sightings of hedgehogs and frogs compared to the rest of the UK.
- Toads were found to be in gardens frequented by frogs but seldom in gardens without frogs (toads were spotted by 25% of garden owners, frogs by 58%).
All five key species were chosen due to their decline or fluctuation in number over the past few years.

The Wildlife Trusts (TWT) is a partnership of 47 Wildlife Trusts across the UK, plus the Isle of Man and Alderney. The vision is an environment richer in wildlife for everyone and TWT is the largest UK charity dedicated exclusively to conserving all habitats and species, with a membership of more than 600,000 people including 100,000 junior members. TWT campaigns for the protection of wildlife and invest in the future by helping people of all ages to gain a greater appreciation and understanding of wildlife. Collectively, the charity also manages more than 2,500 nature reserves spanning over 80,000 hectares.
